ROXUL® Commercial Insulation products provide a number of solutions for building envelope applications. From exterior continuous insulation to interior batts and boards, ROXUL products deliver performance from the day the building is completed.

Our fire-resistant, water repellent and sound absorbent batts and boards can be used to help achieve improved thermal performance and lower energy costs associated with heating and cooling.

ROXUL offers a number of products to meet your project’s needs:

Exterior Cavity Wall: CAVITYROCK®DD and CAVITYROCK® MD are used in exterior cavity and rainscreen applications as an insulating layer by providing valuable thermal, fire and moisture protection

Exterior Sheathing: COMFORTBOARD™ CIS is able to provide an exterior sheathing solution by providing a continuous insulation layer for improved thermal performance.

Curtain Wall: ROXUL SAFE® with CURTAINROCK®, CURTAINROCK® 40 or CURTAINROCK® 80 provide a comprehensive critical line of defense in fire protection that has been UL/ULC tested and approved for perimeter fire containment.

Parking Garage: ROCKBOARD® PG is designed to help improve the performance of Parking Garages by reducing energy costs and providing a layer of safety from fire and water.

Metal Building: FIREWALL® 1HR and FIREWALL® 2HR provide UL/ULC tested wall solutions for metal building and fire-rated wall assemblies. ROXUL Plus® MB is designed for metal building construction where an hourly fire rating is not required.

Roofing

ROXUL roofing boards are designed to perform for the long-term and provide unique fire resistance and water repellency. ROXUL roofing products actually see improved thermal performance at colder temperatures and are backed by a Limited Thermal Warranty for 30 years, guaranteeing 100% of the thermal performance.

TOPROCK® DD is a dual density roof board that combines stone wool’s properties of fire resistance and water repellency with a long-term stable R-value to meet the design needs of today’s roofs. TOPROCK® DD Plus offers a bitumen-coating for torch and mop applications, removing the need for an additional layer of material.

MONOBOARD® is a high-density stone wool board for coverboard applications, providing added thermal and fire resistant properties to the top layer of the roof assembly. MONOBOARD® Plus provides a bitumen-coating for torch and mop applications, allowing the membrane to be applied directly to the product.

Fire Resistant

ROXUL products are fire resistant and do not contribute to the spread of fire and smoke, reducing the risk of fire spreading and allowing additional time for the evacuation of commercial buildings. ROXUL products can withstand up to 2150°F (1177°C) without melting.

Water Repellent

The unique properties of stone wool insulation helps repel water, allowing water to bead and run off the insulation. ROXUL products are also vapor permeable allowing vapor to diffuse throughout the product and contributing to increase drying potential, and a more breathable, energy efficient building. Rather than moisture building up in the layer, ROXUL commercial products will allow the moisture to escape.

Long Term Performance

When installed correctly, ROXUL products maintain their performance for the length of the building. This means the performance you get in Year 1 will be the same each successive year.

ROXUL Products are also dimensionally stable, reducing the amount of shrinkage or gaps prevalent in other insulation products, which can cause reduced system performance due to air leakage.
